Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a multi-channel infusion control method and a multi-channel infusion workstation. Background Art

[0002] Existing infusion equipment mainly includes two types: syringe pumps and infusion pumps.

[0003] A syringe pump, also known as a micro pump, is a commonly used medical device. Its working principle is to use a program-controlled power device to drive a propulsion mechanism to perform linear motion. The propulsion mechanism then pushes the piston rod of the syringe to generate positive pressure to achieve the purpose of infusing liquid into the human body or animal body. Clinically, when liquid drugs need to be injected into the human body or animal body, a syringe pump can be used to achieve the purpose of accurate drug administration or long-term continuous drug administration.

[0004] An infusion pump, also known as a volumetric pump, is an instrument that can accurately control the number of infusion drops or the infusion flow rate to ensure that the drug can enter the patient's body at a uniform speed, accurate dosage and safely to take effect. At the same time, the infusion pump can also improve the efficiency and flexibility of clinical drug administration operations and reduce nursing workload. An infusion pump is usually a mechanical or electronic control device that controls the infusion speed by acting on the infusion catheter. It is often used in situations where the infusion volume and drug dosage need to be strictly controlled, such as when using pressor drugs, antiarrhythmic drugs, intravenous infusions for infants or intravenous anesthesia.

[0005] In clinical practice, when neonatal patients with heart malformations and heart failure are receiving infusions, the requirements for the infusion flow rate and total drug volume / total liquid volume are very strict; if the infusion flow rate is too fast, or the total infusion volume is too large, it will cause a serious burden on the patient's heart, and in severe cases, it may even cause the patient's death.

[0006] Among the infusion products currently on the market, only a single pump has the function of limiting the infusion flow rate and the total drug volume / total liquid volume; if multiple pumps are used to infuse the same patient, medical staff can limit the infusion flow rate and the total drug volume / total liquid volume of a single pump, but in the case of infusing multiple pumps together, the total infusion flow rate and the total drug volume / total liquid volume of multiple pumps still need to be manually calculated by medical staff, otherwise it is likely to cause harm to the above-mentioned sensitive patients; if information is not properly transmitted when medical staff are handing over shifts or medical staff make mistakes in calculations, it may also cause overinfusion, thereby causing serious medical accidents. Summary of the invention

[0007] The object of the present invention is to provide a multi-channel infusion control method and a multi-channel infusion workstation to solve the problem that the total infusion amount and the total flow rate are easily exceeded in the existing infusion operation.

[0013] In one embodiment of the multi-channel infusion workstation, the infusion device is provided with a unit time selector, and the unit time selector is used to set the unit time to 1 hour or 24 hours.

[0016] In one embodiment of the multi-channel infusion workstation, the box is provided with a power supply assembly structure, and the power supply assembly structure includes an electrically conductive power supply slot and a power supply column; the power supply slot is provided at the lower part of the outer surface of the back plate, and the power supply column is provided at the upper part of the outer surface of the back plate, and the power supply column is used to make a plug-in electrical connection with the power supply slot of the same type of the box, and the power supply column and the power supply slot are used to connect the power supply line after the box is spliced; a positioning slot is provided on the back of the controller, and the controller and the box are plug-in connected to the power supply column through the positioning slot.

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] from Figure 1 It can be seen that the multi-channel infusion control method described in the embodiment of the present invention includes the following steps:

[0035] Each infusion device 10 generates an infusion signal according to its own infusion situation, and each of the infusion signals is sent to the controller 20;

[0036] The controller 20 obtains the current total infusion amount according to each of the infusion signals. When the current total infusion amount is greater than the preset infusion amount within a unit time, the controller 20 issues an alarm.

[0037] The controller 20 also derives the current total infusion flow rate according to each of the infusion signals. When the current total infusion flow rate is greater than a preset infusion flow rate, the controller 20 issues an alarm.

[0038] For example, assuming that there are two infusion devices 10, the unit time is 1 hour, and the preset infusion volume is A, then the current infusion volume of the first infusion device 10 is A1, and the current infusion volume of the second infusion device 10 is A2. If A1+A2>A, that is, the current total infusion volume of the two infusion devices 10 is greater than the preset infusion volume, the controller 20 will issue an alarm to promptly notify the medical staff to handle it; among them, when A1+A2=A, that is, the current total infusion volume is equal to the preset infusion volume, at this time the controller 20 can be set to issue or not issue an alarm, but in order to prevent the infusion device 10 from continuing to infuse and causing the current total infusion volume to be greater than the preset infusion volume, the controller 20 can also be set to issue an alarm when the current total infusion volume is equal to the preset infusion volume.

[0039] Similarly, it can be assumed that there are two infusion devices 10, and the preset infusion flow rate is B. At this time, the current flow rate of the first infusion device 10 is B1, and the current flow rate of the second infusion device 10 is B2. If B1+B2>B, that is, the current total infusion flow rate of the two infusion devices 10 is greater than the preset infusion flow rate, the controller 20 will issue an alarm to promptly notify the medical staff for processing; among them, when B1+B2=B, that is, the current total infusion flow rate is equal to the preset infusion flow rate, at this time, the controller 20 can be set to issue or not issue an alarm, but in order to avoid the infusion device continuing to infuse and causing the current total infusion flow rate to be greater than the preset infusion flow rate, it can also be set that when the current total infusion flow rate is equal to the preset infusion flow rate, the controller 20 also issues an alarm.

[0040] It should be pointed out that the total infusion flow may not be greater than the preset infusion volume, but the total infusion flow rate is greater than the preset infusion flow rate. If the infusion flow rate is not controlled in time, it may endanger the patient's life safety. Therefore, the total infusion flow is accumulated in a unit time, and the total infusion flow rate needs to be monitored in real time.

[0041] Among them, the unit time described in this embodiment is mainly preset by the manufacturer according to demand, but in order to meet the different usage needs of medical staff, the unit time can be set to have a certain selection space. For example, the unit time can be set to include two options of 1 hour and 24 hours. Medical staff can perform 1 hour infusion monitoring or 24 hours infusion monitoring as needed, which greatly improves the operational convenience of medical staff.

[0042] Of course, the unit time is not limited to the two options of 1 hour and 24 hours. It can also be set to a time range for medical staff to adjust. For example, an adjustable range of 1 to 48 hours can be provided, and medical staff can set the monitoring time within this range as needed.

[0043] In addition, the infusion device 10 described in this embodiment can be the same type of infusion device or different types of infusion devices. In the prior art, infusion devices are mainly injection pumps and infusion pumps, so the infusion device 10 can be set as an injection pump and / or an infusion pump, that is, the multi-channel infusion control method can be used to monitor and manage multiple injection pumps, and can also be used to monitor and manage multiple infusion pumps, and can also be used to synchronously manage multiple injection pumps and infusion pumps, greatly expanding the scope of application.

[0044] from Figure 1 and Figure 2 It can be seen that the embodiment of the present invention also discloses a multi-channel infusion workstation, which applies the multi-channel infusion control method described in the above embodiment, including the controller 20 and multiple infusion devices 10; each of the infusion devices 10 generates the infusion signal according to its own infusion situation, and each of the infusion signals is sent to the controller 20; the controller 20 obtains the current total infusion amount according to each of the infusion signals, and when the current total infusion amount is greater than the preset infusion amount within a unit time, the controller 20 issues an alarm; the controller 20 also obtains the current total infusion flow rate according to each of the infusion signals, and when the current total infusion flow rate is greater than the preset infusion flow rate, the controller 20 issues an alarm.

[0045] At this time, there are many ways to obtain the infusion volume and infusion flow rate. For example, taking the infusion device 10 as a syringe pump, a laser sensor can be set on the syringe pump. The laser sensor is arranged relative to the push head of the syringe pump. At this time, the laser sensor can monitor the movement distance of the push head per unit time, so as to calculate the infusion volume and infusion flow rate; or the syringe pump has a built-in program, which can calculate the infusion volume and infusion flow rate through a preset algorithm by recording the working time of the syringe pump; that is, the technical personnel in this field can select the appropriate monitoring method according to their needs; and the control method of the multi-channel infusion workstation is consistent with the control method of the multi-channel infusion control method, so it will not be described here.

[0046] Similarly, the multi-channel infusion workstation can also set the infusion device 10 as a syringe pump and / or an infusion pump, that is, the multi-channel infusion control method can be used to monitor and manage multiple syringe pumps, and can also be used to monitor and manage multiple infusion pumps, and can also be used to synchronously manage multiple syringe pumps and infusion pumps, greatly expanding the scope of application.

[0047] like Figure 1 As shown, in order to realize the selectability of the unit time, the infusion device 10 can be provided with a unit time selector 11, and the unit time selector 11 is used to set the unit time to 1 hour or 24 hours; for example, the infusion device 10 is often operated by buttons or touch screens, and at this time the user can control the unit time selector 11 to set the unit time to 1 hour or 24 hours, and the unit time selector can be a timer, and the timer has two working modes of 1 hour timing and 24 hour timing, and the unit time can be selected by switching the working mode.

[0048] like Figure 2 As shown, in order to facilitate the collection and arrangement of the infusion devices 10, the multi-channel infusion workstation may be provided to further include a box body 30; the box body 30 includes a back plate 31 and two side plates 32, the two side plates 32 are respectively arranged on opposite sides of the back plate 31, an assembly cavity 33 is surrounded between the back plate 31 and the side plates 32, a plurality of the infusion devices 10 are arranged in an up-and-down manner in the assembly cavity 33, and each of the infusion devices 10 is detachably installed in the assembly cavity 33; the box body 30 is electrically connected to the controller 20, and the box body 30 is used to transmit the infusion signal to the controller 20.

[0049] At this time, multiple infusion devices 10 are arranged in an up-and-down arrangement, which can avoid the infusion devices 10 being placed randomly, not only reducing the space occupied by the infusion devices 10, but also facilitating medical staff to operate and maintain them; wherein, the controller 20 can be a simple sound alarm or a light alarm, but in order to remind medical staff of infusion abnormalities more promptly, it is advisable to set both a sound alarm and a light alarm.

[0050] In order to realize the detachable separation structure between the infusion device 10 and the box body 30, various methods can be used, such as tightening and fixing with screws, snap-fitting installation, supporting with a support plate, etc. Among them, a preferred detachable separation structure is as follows Figures 2 to 4 As shown, at this time, each of the infusion devices 10 is provided with guide grooves 12 on two opposite sides, and a plurality of groups of guide rails 34 are provided in the assembly cavity 33. The plurality of groups of guide rails 34 are arranged in an up-and-down arrangement in the assembly cavity 33, and each group of the guide rails 34 is installed on the inner surfaces of the two side panels 32, and each group of the guide rails 34 is used to be inserted into the guide groove 12 of one of the infusion devices 10.

[0051] At this time, the guide groove 12 is a straight groove, and the guide rail 34 is a straight rail, so the infusion device 10 can be plugged in and out in a straight direction, and the operation is simple and convenient; Figure 2 As shown, in order to ensure that the infusion device 10 is securely installed, a corresponding locking structure 35 may be further provided on the box body 30 , so that after the infusion device 10 is loaded into the box body 30 , the installation position of the infusion device 10 may be locked by the locking structure 35 .

[0052] In order to realize signal transmission between the infusion device 10 and the controller 20, a data cable can be used to realize signal transmission between the two. However, since there are multiple infusion devices 10, this will lead to too many cables, which will not only appear messy but also inconvenient for subsequent maintenance. Therefore, in order to solve this problem, a signal receiving port (not shown) can be provided on the inner surface of the back panel 32, and a signal output port (not shown) can be provided on the back side of the infusion device 10. The signal receiving port and the signal output port are electrically connected by plugging and unplugging; the connection between the signal receiving port and the signal output port is used to connect the signal transmission path between the controller 20 and the infusion device 10.

[0053] When the infusion device 10 is inserted into the assembly cavity 33, since the signal receiving port and the signal output port are aligned with each other, as long as the infusion device 10 is assembled in place, the signal receiving port and the signal output port will be plugged into each other, thereby realizing signal transmission between the infusion device 10 and the control circuit; and when the infusion device 10 is pulled out, the signal receiving port and the signal output port will also be separated from each other, thereby releasing the electrical connection between the infusion device 10 and the controller 20. The whole process is simple and convenient, and there will be no problem of exposed cables, which is also convenient for medical staff to organize and maintain.

[0054] In actual use, since multiple infusion devices 10 are installed in the box 30, in order to avoid cluttered lines, multiple infusion devices 10 should share one power input, that is, the relevant power supply lines will be arranged in the box 30. As long as the box 30 is connected to the power supply, multiple infusion devices 10 and the controller 20 can be powered at the same time.

[0055] However, the number of infusion devices 10 used is not constant. It may be necessary to increase the number of infusion devices 10 according to the patient's condition. Therefore, in order to realize the additional application of the infusion device 10, multiple boxes 30 can be assembled and used. However, if each box 30 needs to be connected to a power supply, the lines will be messy and difficult to maintain. Therefore, in order to solve this problem, Figure 5 , Figure 7 and Figure 8As shown, the box 30 may be provided with a power supply assembly structure 36, and the power supply assembly structure 36 includes an electrically conductive power supply slot 361 and a power supply column 362; the power supply slot 361 is provided at the lower part of the outer surface of the back plate 31, and the power supply column 362 is provided at the upper part of the outer surface of the back plate 31, and the power supply column 362 is used for plugging and unplugging electrical connection with the power supply slot 361 of the same type of the box 30, and the power supply column 362 and the power supply slot 361 are used to connect the power supply line of the box 30 after splicing; a positioning slot is provided on the back of the controller 20, and the controller 20 and the box 30 are plugged and unplugged through the positioning slot and the power supply column 362.

[0056] Therefore, when a single box 30 is used, it is only necessary to connect the power supply slot 361 to the mains, and the box 30 can power each infusion device 10 and the controller 20; when multiple boxes 30 are spliced ​​and used, as long as the bottom box 30 is connected to the mains through the power supply slot 361, the electric energy will be transmitted to each box 30, so that each box 30 can power the assembled infusion device 10.

[0057] It should be noted that when the boxes 30 are spliced ​​for use, since there is only one controller 20, it is particularly important to realize that each box 30 collects the infusion signal and sends it to the controller 20. To solve this problem, Figures 5 to 8 As shown in the arrangement, the box 30 is provided with a communication assembly structure 37, and the communication assembly structure 37 includes an electrically conductive signal transmission socket 371 and a signal transmission plug-in 372; the signal transmission socket 371 is arranged at the lower part of the outer surface of the back panel 31; the signal transmission plug-in 372 is arranged at the upper part of the outer surface of the back panel 31, the signal transmission plug-in 372 is electrically connected to the signal receiving port, and the signal transmission plug-in 372 is used to make a plug-in electrical connection with the signal transmission socket 371 of the same type of the box 30; the signal transmission socket 371 is also provided on the back of the controller 20, and the controller 20 and the box 30 are electrically connected by the signal transmission socket 371 and the signal transmission plug-in 372.

[0058] Therefore, when a single box 30 is used, after the box 30 receives the infusion signals of each infusion device 10 through the signal receiving port, the infusion signals will be sent to the controller 20 via the communication assembly structure 37; when multiple boxes 30 are spliced ​​and used, the lower box 30 will send the infusion signals to the upper box 30 via the communication assembly structure 37. After this repeated operation, the infusion signals collected by each box 30 can be aggregated and sent to the controller 20, so that the controller 20 can uniformly control the infusion devices 10 in multiple boxes 30.

[0059] Among them, at this time, the box body 30 can also power the controller 20 through the communication assembly structure 37, avoiding the need to add a power supply structure and also helping to improve the structural compactness of the product.

[0060] In addition, the signal transmission socket 371 and the signal transmission plug-in 372 have a variety of options, as long as it is a plug interface that can realize signal transmission. Among them, since USB has a wide range of applications and good effects, it is preferred to set the signal transmission socket 371 and the signal transmission plug-in 372 to use USB to achieve plug-in connection.

[0061] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
